William H. C. Hall II, 58, a consultant in international finance telecommunications, was killed Wednesday in a traffic accident in Falls Church, where he lived.

A Falls Church police spokesman said Mr. Hall's car and a truck collided at S. Washington Street and Annandale Road. He was pronounced dead at Arlington Hospital.

Mr. Hall came here in the mid-1950s to work for Page Communications, which sent him to France for 2-1/2 years. He returned to Falls Church in 1959 and worked for Page until 1961. He then moved to Ankara, Turkey, as president and general manager of TAI, a telecommunications division of Melpar. After four years, he divided his time between Turkey, Iran and the headquarters offices here.

Mr. Hall returned permanently to Falls Church in 1978, when he became a consultant to TAI. He set up his own consulting business a year later.

He was born in Wilmington, N.C. After serving with the Army Corps of Engineers in Europe in World War II, he earned a degree from North Carolina State University.

His marriage to the former Marguerite Vaughn ended in divorce.

Survivors include two daughters, Susan Dilda of Falls Church, and Laura Shields of Raleigh, N.C.; three sons, Wallace Kenneth, of Falls Church, and Stephen Hankins and Mark Thomas, both of Wilmington; his mother, Olive Ewing Hall of Wilmington; a brother, Phillip, of Elizabeth, N.J.; a sister, Mary V. Jones of Wilmington, and two grandchildren.
